This paper looks highly promising, but here's the rub: these safer solvents with reactive organometallic reagents need to become commercially available. The authors added the safer solvents to commercial preparations, then removed the hexanes or whatever. This isn't going to happen in the 'real world' laboratory and you still have the flammability issue while removing the higher-flammability solvent.

SO--is this something CHAS can push for with the major vendors/manufacturers of these reactive organometallic reagents??

Dear CHAS,

My old grad school advisor recently published a paper entitled "Safer solvents for reactive organometallic reagents" in Tetrahedron Letters. It may be of some interest to those in DCHAS.
